IONIC
LAMELLA PLATE
CLARIFIER Small in size - big in performance
Ionic Lamella plate clarifier configuration ensures laminar flow conditions, which results in hydraulic
uniformity and high effluent quality. It permits great reduction in the space needed for clarification
equipment and allows the compact equipment to be located indoors if desired, or to be easily relocated at
a later date. It also makes point-source treatment not only feasible, but logical for many applications. The
Lamella Clarifier system consists of a series of inclined overlapping plates, which are arranged to form
separate sedimentation chambers or cells between each pair of adjacent plates. The overlapping additive
projected area of the plates is a factor of increased surface settling which is proportional to the number of
plates used.
KEY ADVANTAGES OF LAMELLA CLARIFIER SYSTEM
No moving parts, thereby minimizing maintenance.
Time required to stabilize the Lamella Clarifier system after start up is only approximately 20 minutes.
Continuous operation possible for any length of time without shutdown
Sludge thickener zone having four sloped hopper bottoms replaces the extra thickener
Maximum projected effective settling area(PESA) per m2 of plate area available due to better hydraulic
distribution and collection systems
Each plate is constructed of FRP corrosion resistant material
Lifting arrangements are not required for plate installation or inspection individual Lamella plates can be
easily removed and installed during installation or maintenance by a single operator without the need to
shut down the system
Internal flow feed ducts ensure even distribution of water to each and every plate controlling velocity and
thereby minimizing turbulence
Adjustable weir plates ensure even collection of the treated water without short circuiting
The tank and structural support design is completely self supporting for continuous working conditions and
is also compatible with supporting walkways, ladders etc. The flash mix cum flocculation tank is a one piece
configuration for bolt up to the lamella tank in the field.
Manual floor space and building height clearances required
The Lamella Clarifier system design is such that it does not build up deposits, thereby minimizing the
frequency of cleaning as well as other maintenance problems usually faced with conventional clarification
systems
Small in Size- Big in Performance
Flow Entry:
In the Ionic lamella clarifier, flow enters form both sides of
the lamella plate. This allows the feed flow to be equally
proportioned, directed and distributed to all settling
surfaces without impeding the movement of solids already
settled. The inlet flow is divided and enters the lower part
of each sedimentation cell from its two opposite sides. As
the water is displaced upward in smooth, gentle flow, the
suspended solids coalesce to form precipitates which
settle in the chambers on the lower portion of each
lamella plate influent water flows upwards over the
plates. The deposited precipitates increase in size until
they slide or roll down the inclined surface of the plates.
This is then collected in the hopper provided at the bottom
of the separator.
Weir Take Off:
A weir plate with custom-sized orifice holes is used to
provide more effective collection designs. The orifices are
positioned so that each compartment bounded by a pair of
plates is serviced by an orifice on each side. This results in
more efficient hydraulic conditions and thus higher effluent
quality. Near the top of each plate, clarified water leaves
each cell through a pair of circular openings in the
adjustable weir plate located along each side of the
separator tank. The weir plate should be set horizontally in
order to provide a design water level which is lower than
the top of the tank.
Hopper Arrangement:
Several options are available for sludge storage. The
standard arrangement is a four sided, inverted pyramid,
hopper bottom. A second option is to mount the lamella on
top of a mechanical thickener in order to achieve a higher
solids concentration, while at the same time providing a
large liquid sludge storage volume. The sludge which is
formed is periodically removed by opening the drain valve
in the hopper bottom of the settling tank. Continuous
sludge bleed off is recommended depending on the
suspended solids load, in order to utilize the maximum
volume of the settling zone effectively.
Optionally during periods of low turbidity, part of the
sludge formed is recycled back into the flash mix cum
flocculation tank to increase efficiency of the system.
Principle of Operation
The flash mix cum flocculation tank is divided
internally into two compartments. Water to be
treated is fed into the bottom of the flash/static
mix compartment, where it is thoroughly mixed
with chemicals. The partition plate dividing the
tank allows the water to pass over to the
flocculation compartment.
In the flocculation compartment, formation of
flocs continues and flocculation is completed.
Water containing the flocs passes into the Lamella
Plate clarifier. The flow is divided after the water
enters the Lamella at the lower part of each
sedimentation cell, from its opposite sides. As the
water moves upwards along the inclined plate,
suspended solids coalesce to form precipitates
which settle at the bottom of the plate. The
clarified water continues to flow upward along
the plate until it reaches the top of the plate and
thereafter flows over the adjustable weird outlet
onto the outlet of the Lamella System. The
precipitate slides downward into the hopper
bottom of the Lamella clarifier system, from
where it is periodically removed for suitable
disposal.
